BACKGROUND OF THE INVENTION

I. Field of the Invention

The present invention relates to novel tetrahydroisoquinoline derivatives, processes of producing the same and fungicides containing the same as active ingredients.

II. Description of the Related Art

Fungicides are indispensable in agriculture to prevent plant diseases and to increase the yield of the agricultural products. A number of agricultural fungicides are now used. However, some of them have poor fungicidal activities and some of them have restrictions on their use because of their toxicities to environment. Further, when the same or similar fungicides are used for a long time, pathogenic plant fungi which are resistant to the fungicides are generated, so that the effects of the fungicides are reduced. Thus, a fungicide with sufficient fungicidal activity, which is free from the problems on the pollution of environment and on the emergence of drug-resistant fungi is demanded.

Tetrahydroisoquinoline skeleton is contained in the benzophenanetrizine alkaloids and various physiological activities thereof including anti-cancer activity are known (e.g., J. Am. Chem. Soc. 1983, 105, 2873; J. Org. Chem. 1978, 43, 286). However, the present inventors found novel tetrahydroisoquinoline derivatives having fungicidal activities.

Accordingly, an object of the present invention is to provide a novel compound effective as a fungicide with sufficient fungicidal activity and which is free from the problems on the pollution of environment and on the emergence of drug-resistant fungi.

In the pair of enantiomers in which the methine hydrogen on the 4-position of the isoquinoline ring emerges in the side of higher magnetic field in ¹ H-NMR spectrum (in DMSO-d₆ solvent), the coupling constant between the methine hydrogen on the 4-position and the methine hydrogen on the 3-position of the isoquinoline ring is J=0 Hz, so that these isomers are assumed to have trans form (J. Org. Chem. 1978, 43, 286). This pair of enantiomers is herein after referred to as "trans compound".

Both the cis compound and trans compound, as well as mixtures thereof are effective as fungicides.

The tetrahydroisoquinoline derivative of the formula [IV] may preferably be produced by treating the tetrahydroisoquinoline derivative of the formula [III] in the presence of a solvent and a base at 60° C. to 250° C., preferably 100° C. to 200° C. for 5 minutes to 200 hours, preferably 30 minutes to 60 hours.

Preferred examples of the base employed in this reaction include carbonates and hydrogen carbonates of alkaline metals such as sodium carbonate, potassium carbonate, sodium hydrogen carbonate and potassium hydrogen carbonate.

The compounds of the present invention do not substantially damage the crops such as rice, wheat and cucumber, so that they are highly safe.

The fungicide according to the present invention, which contains the above-described tetrahydroisoquinoline derivative of the present invention may contain the tetrahydroisoquinoline derivative alone, but usually contains an agriculturally acceptable carrier, surfactant, dispersing agent and/or other additives and is formulated into, for example, wettable powder, emulsifiable concentrate, powder or granules. These formulations may be applied directly or after diluting to an appropriate concentration. The content of the tetrahydroisoquinoline derivative in the fungicide composition may be appropriately selected and may preferably be 0.5-80% by weight with respect to the overall composition.

The amount of the fungicide to be applied to the plants differs depending on the tetrahydroisoquinoline derivative contained therein, the disease to be treated, the degree of the disease, environment and on the formulation form of the fungicide. In cases where the formulation form of the fungicide is one which is directly applied, such as powder or granules, the amount of the fungicide to be applied may preferably be 1-5000 g, more preferably 5-1000 g per 10 ares in terms of the amount of the active ingredient. In cases where the fungicide is finally used in the form of liquid, such as emulsifiable concentrate or wettable powder, the concentration of the active ingredient in the liquid to be applied may preferably be 0.1-10,000 ppm, more preferably 1-3000 ppm.
